Abstract: In this paper, a wideband hexagonal ring antenna with defected ground structure (DGS) which is suitable for wide band applications is designed. The proposed structure has overall dimensions of 50mm×42mm×1.6mm made on the readily available FR4 substrate having permittivity εr 4.4. Later a DGS is introduced on the ground. This antenna operates in wide band starting from 2.4 GHz to 9.8GHz below – 10db. The proposed design supports wireless communication applications such as Bluetooth (2.4GHz), WiMAX (3.5/5.5GHz), WLAN(5.2/5.8 GHz) and C-band applications. Parametric analysis of the design is carried out by the varying radius of circular slot and also by varying the gap between ground and patch there by creating a provision to improve bandwidth. The performance of the proposed design is analyzed with return loss, VSWR, radiation pattern, gain characteristics, current and field distributions. This design is also compared with existing designs and it was found that proposed design shows good result than existing one. The design antenna gives excellent agreement between measured and fabricated results.
